【摘要】 在室内研究了黑肩绿盲蝽对褐飞虱卵的功能反应及搜寻行为。结果表明,黑肩绿盲蝽对主要分布于稻株上中部的褐飞虱卵(在浙农大40上)的功能反应明显地强于对主要分布于稻株中下部的褐飞虱卵的功能反应(在浙852上)。黑肩绿盲蝽在稻株上的搜寻行为属非随机搜索型,在稻株各部位间明显地偏于稻株的上部活动,据此可解释黑肩绿盲蝽在2个品种上功能反应差异的原因。更多还原

【Abstract】 Experiments were conducted in laboratory to study the functional response of the predator, Cyrtorhinus lividipennis (Reuter), to eggs of brown planthopper (BPH), Nilaparvata lugens(Stal) ,and its searching behavior. The results showed that the functional response of the predator to BPH eggs mainly distributing on the upper and middle parts of the rice plants (ZND40) was obviously stronger than that mainly distributing on the middle and lower parts of rice plants (Z852). The predator had an obvious preference for searching on the upper part of rice plants,which indicated that the non-random searching pattern of the predator on rice plants resulted in the difference of functional responses of the predator to BPH eggs on two rice varieties.更多还原
